This has been mentioned elsewhere, longest thread, I think, below (It might be worth going through the thread as there are possible solutions which might work for you in there (though don’t for me)):
I’ve not, as yet, seen any acknowledgement from Steinberg that it is an issue, presumably as it does not happen on all Windows machines (only on one of mine for instance). I think it’s mainly an NVIDIA issue but not certain of that either. Myb we need to riase it on the issues page to get a response from Steinberg at least to acknowledge the issue that some of us are having.
I’m using the following as a semi-solution: Go to Preferences-Record-Audio and un-tick “Record Audio images during Record” then at least after recording the Waveform images do show up…still not ideal but better than nothing I think.
PS: Welcome back…I was an Atari user with Cubase too (I think it was Cubeat back then?).
